Icelandic volcano a lurking threat

DUBLIN - It's been a month now, and Iceland's volcano shows no sign it will stop belching ash across Europe anytime soon. The rolling eruptions threaten more havoc for summer vacation plans and higher costs for struggling airlines.

Although the global disruption of last month's massive eruption has faded, smaller ash plumes snarled air services intermittently over the last week all the way to Turkey - more than 4,100 kilometers from the Eyjafjallajokul (pronounced ay-yah-FYAH-lah-yer-kuhl) volcano.

Air-control authorities and geologists agree that the continent must brace indefinitely for rapid shutdowns of air services as computerized projections try to pinpoint where the ash clouds will float next at the whim of shifting winds.
